i Specification of Letters I Eatent Patented May 11, 1909. 1

Application filed may 22, 19os.- Serial no. 434,334. I

To all whom it may concern:

Be it known that I, WILLIAM J. WILLIAMS,

citizen of the, United States, residing at Franklin, in the county of Venango and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Working Rolls, of whic 1 the following is a specification, reference being had therein to the accompanying drawings.

T e construction of my improved rolls is herein fully set forth, reference being had to the ace-om anying drawings which form a part hereo and in which,

Figure 1 is an elevation of my improved rolls. Fig. 2 is an elevation of the bodyor arbor of the upper roll stripped of its rings, collar and nut. Fig. 3 is an end elevation of Fig. 2. Fig. 4 is a perspective view of one of the notched rings which I employ in constructing one of my rolls. Fig. 5' is a erspective view of one of the plainv rings w ich I employ in. constructing one of my rolls. Fig. 6 is a collar. Fig. 7 is a nut.

The object ofmy invention is to provide an easily and cheaply constructed set of rolls especially for the production of a tie-plate bar, such as is shown in'an application for Letters Patent; for an improved recess of rolling tie-plate bars, WhlCll a p ication is executed and filed at even date erewith and numbered Serial No. 434,336. Said rolls maybe easily adapted to rolling other shapes The construction, of my improved rolls is as follows: In constructing the upper roll, I provide a body or arborFig. 2which has the usual form of bearings 1 and 1, at either end thereof; approximate to the bearing 1, I form a collar consisting of the steps 2, 3, and adjacent to the step 3. is an arbor 4, the office of which will be hereafter specified. Adjacent to the arbor is a threaded section 5, and adjacent to this is the bearing 1. Arbor 4 is provided with suitable keys 6. Upon said arbor I alternately mount rings 7Fig. 4, and rings 8,--Fig. 5; said ring 7' has equally spaced notches formed inits periphery, whic notches are for the obvious purpose of forming studs upon the face of the tie-plate bar.

After the desired number and combination of rings have been located. upon arbor 4, collar 9Fig. 6is placed upon the arbor.

' Said collar as well as rings 7 and 8 are provided with key-seats 6 for the reception of the keys 6. Collar 9, when in position, corresponds to the step 3 at the other side of said rings. For the purpose of securing the 10--Fig. 7which occupies t e screwthreaded portion 5 of. the body. The roll thus completed is shown in Fig. 1.

I do not, however, wish to be understood as limiting myself to the particular number and combination of rings shown in Fig. 1, as the plain and notched rings could beeasily transposed, or one notched ringand several plain ones could be used, andstill be within the spirit and scope of my invention. In the event of any change in the number and location of rings 7 and 8, the bar-groove in the lower roll would be correspondingly modified.

The construction of the lower roll is substantially as follows: The essential feature of rings and collar in position, I em. loy a nut 1 the same is a comparatively deep bar-groove 11 in the bottom of which is formed a number of flange-grooves 12, which grooves 12 preferably corres 0nd in number and vertical alinement wit the notched rings 7. At

each side of said bar-groove are formed collars composed of etc s 13, 14, outside of which, "may be locate bearings of the usual construction,

By the construction above set forth, it will be noted'that the rings 7 and 8 of the upper roll unitedly form a tongue, which occupies a portion of the bar-groove in the lower roll, thus forming a closed pass by which the tieplate-bar, or other article, is caused to have a true, square, and clean out shape, particularly along the edges and at the corners.

My rolls are easy to construct and also easy to keep in repair, and the rings vwhich make up the wearing parts of the upper roll, may be very cheaply, quickly, and easily replaced.

I claim: 1. Metal working rolls consisting of a roll 'havin a body portion, provided with integra y formed flanges forming between them a peripheral groove, combined with a second roll having a removable sectional tongue adapted to operate-in said groove,

and substantially the same width as the v groove to form a closed pass, substantially as shown and described.

2. Metal working rolls consisting of a roll having a body portion provided with integrally formed flanges, forming between them a peripheral groove, combined with a second roll having a removable sectional tongue adapted to operate in said groove, and off-substantially the same width as the groove to form a closed pass, the lateral faces of thesaid tongue and the adjacent faces of said flanges being substantially perpen dicular with theaxes of said rolls. k

3. -Metal-working rolls consisting of aroll having a bar-groove therein, the peripheral face of said groove being suitably conformed and the lateral faces of said groove bein substantially perpendicular to the axis 0 said roll, said bar groove bein formedby integrally formed flanges on t e rolls, in comb1- nation with a roll having atongue of subthe aims of said roll, and means for non-- Pevolubly secnring sald rings in position.

4. Metal working rolls, comprising a roll having integrally formed flanges to provide a periphera groove, a second roll having a sectional removable tongue to cooperate with said groove and of a width substantially the same as that of the groove to form' a closed bar pass, said second roll also having end flanges toprovide grooves between the same and the tongue to receive the flanges of the first roll, substantially as shown and described.

In testimony whereof I afiix my signature in presence of two witnesses.

WILLIAM J. WILLIAMS.
